  2. 6. Mathematical modelling in upper secondary mathematics education in Sweden

    Author : Jonas Bergman Ärlebäck; Christer Bergsten; Bharath Sriraman; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : The aim of this thesis is to investigate and enhance our understanding of the notions of mathematical models and modelling at the Swedish upper secondary school level. Focus is on how mathematical models and modelling are viewed by the different actors in the school system, and what characterises the collaborative process of a didactician and a group of teachers engaged in designing and developing, implementing and evaluating teaching modules (so called modelling modules) exposing students to mathematical modelling in line with the present mathematics curriculum.

  4. 7. The Chevreton tensor and its trace

    Author : Ingemar Eriksson; Marc Mars; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we investigate the Chevreton tensor in Einstein-Maxwell theory. It was introduced in 1964 as the counterpart, for electromagnetic fields, of the well-known Bel-Robinson tensor of the gravitational field. We prove that, in the absence of electromagnetic sources, this tensor is completely symmetric. READ MORE

  5. 8. The Double Obstacle Problem on Metric Spaces

    Author : Zohra Farnana; Jana Björn; Anders Björn; Jan Malý; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we investigate the double obstacle problem for p-harmonic functions on metric spaces. We minimize the p-energy integral among all functions which have prescribed boundary values and lie between two given obstacles. READ MORE

  6. 9. Mathematical modelling in upper secondary school in Sweden : An exploratory investigation

    Author : Peter Frejd; Christer Bergsten; Jonas Ärlebäck Bergman; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : The official curriculum guidelines for upper secondary school in Sweden emphasise the use of mathematical models and mathematical modelling in mathematics education. However, no explicit definitions or descriptions of the notions are given in the curriculum. READ MORE

  7. 10. The k-assignment Polytope and the Space of Evolutionary Trees

    Author : Jonna Gill; Svante Linusson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; k-assignment; polytope; Birkhoff polytope; bipartite graphs; MATHEMATICS; MATEMATIK;

    Abstract : This thesis consists of two papers.The first paper is a study of the structure of the k-assignment polytope, whose vertices are the m x n (0; 1)-matrices with exactly k 1:s and at most one 1 in each row and each column. READ MORE
